Given numbers are 119, 110, 638, 990

The list of prime factors of all numbers are

Prime factors of 119 are 7 x 17

Prime factors of 110 are 2 x 5 x 11

Prime factors of 638 are 2 x 11 x 29

Prime factors of 990 are 2 x 3 x 3 x 5 x 11

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 119, 110, 638, 990

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(119, 110) = 13090

GCD(119, 110) = ( 119 x 110 ) / 13090

= 119 / 110

= 119

Step2:

LCM(1, 638) = 638

GCD(1, 638) = ( 1 x 638 ) / 638

= 1 / 638

= 1

Step3:

LCM(1, 990) = 990

GCD(1, 990) = ( 1 x 990 ) / 990

= 1 / 990

= 1

So, Greatest Common Divisor of 119, 110, 638, 990 is 1
